(Note 2) When 2-phase pulse is used, maximum frequency of phase-A and B are different
(32kHz for A-phase, 2kHz for B-phase). In order to detect rotation direction over 2kHz,
choose detection methods in P004.

01 90 ph. difference 2-ph. pulse train 1
02 90 ph. difference 2-ph. pulse train 2
(Note 3) For rotating coordinate system, if "" is set in , the rotation direction of shorter
routing is selected. In this case, set the number of pulse for one rotation in position-0
(). This value must be positive number. When "" is set in , 
.
or
(Note 4)  is cleared by inputting PCLR, SPD, ORG, RS signal or turning on the power
supply.
When "" is set in , PCLR is effective only during the RUN command (FW, RV) is
given.
(Note 5)  is to be set higher when speed detection is not accurate in low speed.
